regex replace every 2nd occurrence with Javascript

I would like to replace some keywords to HTML elements in a textarea with javascript. Is there any way to replace every 2nd string that has been found?

Just for an example what I mean is: if there are 6 $ signs in the string, the first, third, and fifth would be replaced to HTML tag and the rest to </strong> HTML tag.

Do the match and replace in pairs with a capture group between them:

string = 'This is a $word$ and $two words$ and a $phrase with several words$.';
newstring = string.replace(/\$([^$]*)\$/g, '<strong>$1</strong>');
console.log(newstring);
